i play for leisure with a mouse on a pc and I'm not a pro or anything. Yet, i'm way smoother, faster and accurate at the same time. I mean I can headshot pretty often within 50ms. This guy needs a full second on NON-MOVING targets in counterstrike. He would have zero chance against a mouse user. zero.

Remember that this guy played with the controller for a long time and his job is to make it look like as good as possible.

So yeah, the controller seems ABSOLUTELY fine for a controller (and probably more precise in some cases than a "regular" controller), but please, let's not fool ourselves, this is NOT a PC gaming experience - i.e. this is very far from the level of control a MOUSE provides.
